Definitions
- the present invention relates to a tape unwinding device for a machine for stamping sheet-like elements.
- the invention also relates to a stamping machine configured to deposit on each sheet of gold or metallized film from at least one strip to be stamped.
- Each strip to be stamped is packaged in the form of a reel which is mounted so that it can rotate on itself, and which is unwound via a feed shaft pulling directly on the strip.
- this feed shaft is doomed to rotate at variable speed since the belt feed takes place sequentially within the platen press.
- the coil has a mass and therefore a relatively high inertia, it is particularly difficult for it to follow such a succession of accelerations, decelerations and time delays.
- document WO2012 / 116781 discloses a tape unwinding system which takes place between the reel and the feed shaft, and which implements two series of references whose spacing is likely to vary in band advance function.
- the two series of references are arranged so as to define a strip circulation path, the shape of which describes a succession of loops which respectively bypass each reference passing alternately from one series of references to the other.
- One of the series of references is mounted movable in displacement relative to the other, between a position close together in which the series of references are arranged close to each other so as to define a strip circulation path of minimum length, and a distant position in which said series of references are arranged at a distance from each other the other so as to define a strip circulation path of maximum length.
- this tape unwinding system can generate jolts due to the inertia of the reel, especially during the transient start-up, acceleration stop and deceleration phases. These jolts can stretch the strip and damage it.
- a reel braking device is also generally necessary to guarantee optimum belt tension and not to unwind the reel more than necessary when the feed shaft idles and stops.
- Another drawback of this system is that it can be difficult to implement, in particular following a production malfunction.
- Another problem also is that the outsourced system requires a space on the ground and a deployment of tape between the reel and the press which are significant. This large length of unrolled tape can affect the accuracy of removal and increase the length of tape consumed.
- One of the aims of the present invention is to propose a device for unrolling a strip to be stamped making it possible to at least partially resolve at least one of the abovementioned drawbacks.
- the subject of the present invention is a strip unwinding device for a stamping machine capable of accumulating strip to be stamped in a pre-unwound form between at least one stamping reel and a platen press.
- the stamping machine characterized in that the tape unwinding device comprises:
- a central drum configured to be driven in rotation at a variable speed of advance, integral in rotation with an axis of the tape unwinding device
- a satellite roller having an axis arranged parallel to the axis of the central drum, the satellite roller being capable of rotating around the central drum, the pre-unwound strip being capable of winding around the central drum under the effect of displacement from the satellite roll, and
- a planetary drive device for moving the satellite roller around the central drum as a function of the difference in rotation speeds of the central drum and an outer ring of the planetary drive device configured to be driven in rotation at constant speed in a direction of rotation opposite to the direction of rotation of the central drum.
- the stamping strip can thus be pre-unwound at constant speed of the spool stamping, pulled by the satellite roller.
- the tape can be delivered at the output of the tape unwinding device at the variable feed speed.
- the length of the accumulated strip to be stamped varies with the angular displacement of the satellite roller around the central drum, which varies due to the planetary drive, as a function of the difference in the speeds of rotation of the central drum and the outer ring. It is thus possible to accumulate the strip to be stamped then to deliver the strip to be stamped accumulated with each request of the advance shaft.
- the tape unwinding device is more compact than a "linear" system of the prior art because it can be integrated directly into the machine. It is also more robust and easier to use.
- the distance between the spool and the press can be small, which increases the accuracy of tape deposition and therefore reduces the tape consumed.
- the planetary drive device comprises:
- At least one satellite pinion mounted on the planet carrier, meshing the outer ring and the central pinion to be rotated in one direction or the other around the central drum depending on the difference in the rotation speeds of the central drum and the outer crown.
- the pitch radius of the central pinion corresponds to the outside radius of the central drum.
- the diameter of the satellite roller has a dimension smaller than the radial gap located between the pitch diameter of the outer ring and the outer diameter of the central drum.
- the satellite roller is rotary.
- the planetary drive device further comprises a toothed wheel mounted on the planet carrier, integral in movement with the satellite roller and meshing the outer ring.
- the pitch radius of the toothed wheel corresponds for example to the outside radius of the satellite roller.
- the satellite roller is fixed to a planet carrier of the planetary drive device, the satellite roller being porous and having an internal cavity configured to be placed in communication with pressurized air so as to form an air cushion under the strip to be stamped.
- the planetary drive device comprises a guide integral with the movement of the satellite roller around the central drum, the guide being capable of being interposed between two strands of the pre-unwound strip to guide an outer strand of said strip. bandaged.
- the guide comprises between one and ten, such as five, additional satellite roller (s), the additional satellite roller (s) and the roller satellite in a circle.
- the additional satellite roller (s) can be rotatable.
- the guide also includes, for example, as many toothed wheels as additional satellite rollers, the toothed wheels being mounted on the planet carrier and integral (s) in rotation with a respective additional satellite roller and meshing the outer ring.
- the guide comprises a metallic element fixed to the planet carrier, the metallic element having between one and ten, such as five fold (s) or corrugation (s), the fold (s) or corrugation ( s) and the satellite roll forming part of a circle.
- the diameter of said circle corresponds to the pitch diameter of the outer crown.
- the outer crown is configured to be rotated at a constant speed substantially equal to an average value of the variable advance speed.
- the axis of the central drum is capable of being rotated at a variable advance speed by a motor of the tape unwinding device to form a feed shaft. This reduces the number of parts.
- the invention also relates to a machine for stamping sheet-shaped elements configured to deposit on each sheet of golden or metallized film from at least one strip to be stamped, characterized in that it further comprises at least one tape unwinding device as described above.

- Figure 12 shows a perspective view of elements of a tape unwinding device according to a second embodiment.
- upstream and downstream are defined with reference to the longitudinal direction of movement of the sheets D ( Figure 1).
- the sheets move from upstream to downstream, generally following the main longitudinal axis of the machine, in a movement clocked by periodic stops.
- outermost-shaped elements and “leaves” will be considered equivalent, and will relate to elements composed of corrugated cardboard as well as cardboard flat, paper or any other material commonly used in the packaging industry. It is understood that throughout this text, the terms “sheet” or “element in sheets” or “element in the form of leaves” very generally designate any print medium in the form of leaves such as, for example , sheets of cardboard, paper, plastic, etc.
- Figure 1 shows an exemplary embodiment of a stamping machine 1 capable of depositing on each sheet of gold or metallized film from at least one stamping strip 2, in particular for the manufacture of packaging.
- This machine 1 is conventionally composed of several work stations 100, 200, 300, 400, 500 which are juxtaposed but interdependent one by one to form a unitary unit capable of processing a succession of sheet-shaped elements.
- a feeder 100 a margin table 200, a stamping station 300, a tape feeding station 400 as well as a receiving station 500.
- a transport device 600 is moreover provided for individually moving each sheet from the output of the margin table 200 to the receiving station 500, including through the stamping station 300.
- the sheets are successively removed from the top of a pile by a suction gripping member which transports them to the margin table 200 directly adjacent.
- the sheets are laid out by the suction gripping member, that is to say placed one after the other so as to partially overlap.
- the entire ply is then driven along a plate in the direction of the stamping station 300, by means of a belt transport mechanism.
- the head sheet can be systematically positioned with precision by means of front and side tabs or by a register system.
- the work station located just after the margin table 200 is therefore the stamping station 300.
- the latter has the function of depositing on each sheet, by hot stamping, metallized film which comes from a strip to be stamped 2. It uses for this a platen press 310 inside which the stamping operation is conventionally carried out, between an upper heated platen 320 which is fixed, and a lower platen 330 which is mounted movable in displacement following a vertical back and forth movement.
- the strip feed station 400 is responsible for ensuring both the supply of the machine 1 with the stamping strip 2 as well as the evacuation of this same strip 2 once it has been used after passing through the station. stamping 300.
- the process for processing the sheets in the stamping machine 1 ends in the receiving station 500, the main function of which is to repackage the previously treated sheets in a stack.
- the transport device 600 is for example arranged so as to automatically release each sheet when the latter is found in line with this new stack. The sheet then falls squarely on top of the stack.
- the transport device 600 implements a series of gripper bars which are mounted movable by means of two chain trains 620 arranged laterally on each side of the stamping machine 1.
- Each chain train 620 runs through a loop which allows the gripper bars to follow a trajectory passing successively through the stamping station 300, the tape feed station 400 and the reception station 500.
- the set of gripper bars will start from a stopped position, accelerate, reach a maximum speed, decelerate, then stop, thus describing a cycle corresponding to the movement of a sheet from a work station to the station next work.
- the 620 chain trains move and stop periodically so that, during each movement, all of the gripper bars engaged with a sheet are passed from one station to the adjacent downstream work station. Each station performs its work in synchronism with this cycle which is commonly called the machine cycle.
- the workstations start a new job at the start of each machine cycle.
- the tape supply station 400 includes at least one tape unwinding device 10 capable of accumulating the strip to be stamped 2 in a pre-unwound form downstream of at least one stamping reel 3 and to deliver the pre-unrolled strip at each request from a machine feed shaft 1.
- the tape unwinding device 10 is interposed between at least one stamping coil 3 and the platen press 310 ( Figure 1).
- the tape unwinding device 10 comprises a central drum 11, a satellite roller 14 and a planetary drive device 15.
- the central drum 11 is configured to be driven in rotation at a variable advance speed, integral in rotation with an axis 16 of the tape unwinding device 10.
- the speed of advance controlled by machine 1 increases then decreases (we speak of "advance") and is canceled.
- This advance step coincides with the strip to be stamped 2 with a sheet for depositing by stamping the metallized film according to a predefined program in the machine 1.
- the advances can be identical or different between each stop or different between at least two successive and periodic stops.
- the satellite roller 14 has an axis 21 arranged parallel to the axis 16 of the central drum 11.
- the satellite roller 14 is capable of rotating around the central drum 11.
- the pre-unrolled strip is capable of being wound around the central drum 11 (over less than one turn) under the effect of the displacement of the satellite roller 14. More precisely, the pre-unrolled strip is wound around of the central drum 11 after having bypassed the satellite roller 14 forming a return of the pre-unwound strip ( Figures 10 and 11).
- the planetary drive device 15 comprises a central pinion 12, an outer ring 13, a planet carrier 17 and at least one satellite pinion 20 ( Figures 4 and 5).
- the central pinion 12 is integral in rotation with the central drum 11 and it is coaxial with the central drum 11 (Figure 6). They are for example fixed to axis 16 ( Figure 4). A bearing supports for example the opposite end of the axis 16.
- the pitch radius of the central pinion 12 corresponds for example to the outside radius of the central drum 11 (FIG. 6).
- the outer ring 13 is toothed (Figure 7). It is coaxial with the central pinion 12 and is configured to be driven in rotation at constant speed.
- constant is meant a substantially constant speed, that is to say for example varying over less than +/- 10% of an average speed.
- the constant speed is for example substantially equal to an average value of the variable advance speed.
- the direction of rotation of the outer ring 13 is opposite to the direction of rotation of the central drum 11.
- the direction of rotation of the outer ring 13 is chosen so that the rotation of the outer ring 13 unwinds the stamping coil 3.
- the outer ring 13 is for example carried by a support 19 rotatably mounted on the axis 16 by means of a bearing ( Figure 4). In the axial direction, the central pinion 12 is interposed between the central drum 11 and the support 19 of the outer ring 13.
- the satellite roller 14 has for example a diameter of dimension smaller than the radial gap located between the pitch diameter of the outer ring 13 and the outer diameter of the central drum 11, which allows an inner strand of the strip to be stamped 2 winding on the central drum 11 to intervene without getting caught between the satellite roller 14 and the central drum 11.
- the planet carrier 17 is integral in movement with the satellite roller 14 around the central drum 11 and coaxial with the central drum 11.
- the planet carrier 17 is for example rotatably mounted on the axis 16 by means of a bearing ( Figure 4).
- the planet carrier 17 is formed on the one hand of a disc 17a, for example solid, having a bearing in the center and on the other hand, of a crown 17b fixed coaxially to the disc 17a and carrying bearings for the axes of the at least one satellite pinion 20 and where appropriate, and as will be seen later on toothed wheels 18 and 24 ( Figures 4, 8 and 9).
- the at least one satellite pinion 20 is mounted on the planet carrier 17. It meshes on the one hand, the outer ring 13 and on the other hand, the central pinion 12 to be rotated in one direction or the other around the central drum 11 as a function of the difference in the speeds of rotation of the central drum 11 and the outer ring 13.
- the movement of the at least one satellite pinion 20 causes the movement of the satellite roller 14 around the central drum 11 which varies the length of the pre-unrolled strip.
- the planetary drive device 15 comprises for example four planet gears 20 mounted on the planet carrier 17, for example inscribed in a cross shape ( Figures 5, 8 and 9).
- the satellite pinions 20 transmit the drives of the outer ring 13 and of the central pinion 12 to the planet carrier 17 integral in movement with the satellite roller 14.
- the satellite pinions 20 are not themselves connected to any satellite roller.
- the diameter of the at least one satellite pinion 20 is for example substantially larger than the diameter of the satellite roller 14.
- the planet gears 20, the central gear 12 and the outer ring 13 are arranged at one end of the axis 16, substantially in the same plane. They are for example received in a box 28 ( Figures 2 and 3).
- This arrangement of the gears is also called “planetary gear” or “planetary drive”, the “interior planetary” or “sun” being the central pinion 12, the “exterior planetary” or “crown” being the exterior crown 13 and the “satellite "Meshing the two planets and rotating around their common axis being the satellite pinion 20, G" common axis "being the axis 16.
- the satellite roller 14 is rotary, and can rotate on itself around its axis 21.
- the stamping strip 2 can thus be wound around the satellite roller 14 without friction.
- the planetary drive device 15 further comprises a toothed wheel 18 mounted on the planet carrier 17, integral in movement with the satellite roller 14 and meshing the outer ring 13.
- the toothed wheel 18 and the satellite roller 14 are for example mounted on the axis 21 at one end of the satellite roller 14 ( Figure 4).
- a bearing supports for example the opposite end of the axis 21 of the satellite roller 14.
- the pitch radius of the toothed wheel 18 corresponds for example to the outside radius of the satellite roller 14.
- the circumferential speed of rotation of the satellite roller 14 then corresponds to the speed of rotation of the outer ring 13 at which the stamping strip 2 is unwound from the stamping reel 3.
- the stamping strip 2 can thus be driven by the satellite roller 14 at the same speed as it is unwound from the stamping coil 3.
- the satellite roller 14 is non-rotating. It is for example fixed to the planet carrier 17.
- the satellite roller 14 can be porous and have an internal cavity configured to be placed in communication with pressurized air so as to form an air cushion under the stamping strip 2 so that the stamping strip 2 can be wound around the satellite roller 14 without friction.
- the planetary drive device 15 further comprises a guide 22 integral in movement with the satellite roller 14 around the central drum 11 ( Figures 8 and 9).
- the guide 22 is capable of being interposed between two strands of the pre-unwound strip 2, an internal strand of the stamping strip 2 being against the central drum 11 and an external strand, to guide an external strand of the strip (FIG. 10 and 11).
- the guide 22 comprises between one and ten, such as five, additional satellite roller (s) 23, the additional satellite roller (s) 23 and the satellite roller 14 forming part of a circle C (FIG. 9).
- the additional satellite rollers 23 and the satellite roller 14 are for example regularly spaced, for example on an arc of a circle between 90 ° and 180 °.
- the guide 22 may also include a holding element 34 for holding and guiding the opposite ends of the additional satellite rollers 23 around the axis 16.
- the additional satellite roller (s) 23 can be rotatable.
- the outer strand of the pre-unrolled strip can thus slide over the additional satellite rollers 23 rotating almost without friction.
- the guide 22 comprises between one and ten, such as five, additional satellite rollers 23 rotating and as many toothed wheels 24 mounted on the holder satellite 17 ( Figure 5 and 8).
- the toothed wheels 24 are integral in rotation with a respective additional satellite roller 23. They are mounted at an axial end of a respective additional satellite roller 23 and mesh with the outer ring 13.
- a bearing can support the opposite end of each additional satellite roller 23.
- the additional satellite rollers 23 and the toothed wheels 24 for example have diameters of dimensions similar to the satellite roller 14.
- the inner strand of the stamping strip 2 can thus be interposed without getting caught between on the one hand, the satellite roller 14 and the additional satellite rollers 23 and, on the other hand, the central drum 11.
- the diameter of said circle C corresponds for example substantially to the pitch diameter of the outer ring 13.
- the circumferential speed of rotation of the additional satellite rollers 23 corresponds to the speed of rotation of the outer ring 13 at which the strip to be stamped 2 is unwound from the stamping reel 3.
- the stamping strip 2 can thus be driven by the additional satellite rollers 23 at the same speed as it is unwound from the stamping reel 3.
- the stamping strip 2 coming from the stamping reel 3 can thus be guided by the additional satellite rollers 23 so that the outer strand follows approximately the original diameter of the outer crown 13, the outer strand being substantially parallel to the inner strand of the strip wrapping around the central drum 11.
- the guide 22 may also comprise a plate 32, or plate elements, fixed to the planet carrier 17 in an arc of a circle to guide the inner strand of the strip to be stamped 2 against the central drum 11 ( Figures 8 to 11).
- the stamping strip 2 is for example oriented tangentially to the additional satellite rollers 23 by an input return 26.
- the strip 2 can be returned horizontally by an output return 27 to guide the strip 2 flat in the plate press 310 ( Figure 1).
- the tape unwinding device 10 to comprise a motor 25 configured to drive the axis 16 of the central drum 11 at a variable advance speed (FIGS. 3 and 4).
- the motor 25 is for example in direct connection with the end of the axis 16.
- the axis 16 integral in rotation with the central drum 11 for unwinding the strip to be stamped 2 thus also forms the feed shaft. This reduces the number of parts.
- the strip unwinding device 10 may further comprise an advance roller 29 pressing the central drum 11 to guarantee good transmission between the strip to be stamped 2 and the central drum 11 ( Figure 1).
- the outer ring 13 can be rotated at constant speed by an additional motor 31 of the tape unwinding device 10 (Figure 3).
- the additional motor 31 drives the outer ring 13 for example via a pulley system.
- the outer ring 13 is driven in rotation at a constant speed, for example at a speed of rotation substantially equal to an average value of the variable advance speed (counterclockwise in the example of FIGS. 10 and 11) .
- FIG. 10 thus illustrates a first extreme position of the satellite roller 14 for which the reserve of pre-unwound tape is maximum. While the satellite roller 14 is moving around the central drum 11 to reach this first extreme position, a deposit of golden or metallized film is carried out on a sheet in the platen press 310.
- FIG. 11 shows an example of a second extreme position of the satellite roll 14 for which the reserve of pre-unwound tape is minimal.
- the stamping strip 2 can thus be pre-unwound at constant speed from the stamping reel 3, drawn by the satellite roller 14.
- the strip can be delivered at the output of the strip unwinding device 10 at variable speed of advance given by the central drum 11.
- the length of accumulated strip 2 varies with the angular displacement of the satellite roller 14 around the central drum 11 which varies due to the planetary drive, as a function of the difference in the rotation speeds of the central drum 11 and the crowned outer 13. It is thus possible to accumulate the strip to be stamped 2 then to deliver the strip to be stamped 2 accumulated with each request of the advance shaft.
- reels 3 can also be unwound with the tape unwinding device 10 if these are delivered to the stamping station 300 with the same feed speed.
- the tape unwinding device 10 is more compact than a "linear" system of the prior art because it can be integrated directly into the machine 1. It is also more robust and easier to implement.
- the distance between the reel 3 and the press 310 can be small, which makes it possible to increase the precision of strip deposition and therefore to reduce the strip consumed.
- the unwinding of the stamping reel 3 can continue to be braked in production by a braking device to guarantee a minimum strip tension but in a much smoother manner, which avoids jolts which can damage the strip. .
- Figure 12 illustrates another embodiment of the tape unwinding device
- the guide 33 comprises a metallic element, such as a metallic foil, such as a sheet, having between one and ten, such as five, folds or corrugations 30.
- the guide 33 may also include a holding element 34 to hold and guide the opposite end of the metal element around the axis 16.
- the folds or undulations 30 and the satellite roller 14 (in the direction radial to the axis 16) are inscribed in a circle, coaxial with the outer ring 13.
- the diameter of said circle corresponds, for example, substantially to the pitch diameter of the outer ring 13.
- the folds or undulations 30 are for example regularly spaced, for example on an arc of a circle between 90 ° and 180 °.
- the outer strand of the pre-unrolled strip can thus slide over the folds or undulations 30 almost without friction.
- the stamping strip 2 coming from the stamping reel 3 can thus be guided by the folds or corrugations 30 so that the outer strand follows approximately the original diameter of the outer crown 13.
- the outer strand is then substantially parallel to the inner strand of the strip which is wound around the central drum 1 1. The more there are folds or corrugations 30 and the more the guiding of the outer strand is circular, which makes it possible to avoid unwinding of the strip.
